The zombies are back twice again. Re-annihilate them with your different guns. You can ricochet your bullets to the wall and ceiling. You can launch a remote controlled rocket or bounce a grenade to ignite it. Whatever you do, you must let the penguin race dominate the once extinct zombies. If you like Zombies vs Penguins 4, you can put it to your favorites. So it can be convenient for you to play later!
